To" an zbliom it may concern Be itknown that I, Jo n. Wmenmacitizen of the United States, residing at Pittsburg, in thecounty of Contra useful Improvements in Combined Hinges and Ladders for Silos, of which the following is a specification.

This nvention relates to a mounting for tion are to provide an outside fastener for afsilo door, whereby it: may be firmly seated in-the jamb at all its corners; to provide a fastener by which the door :may be bodily shifted laterally inwardly away from the jamb and then swung through an arc in a plane close to the inner surface of the silo We A A further object is toprovide a mounting for locking, operating and supporting the door and which also forms, when supertical section showing a door in edge view closed and locked, and one of its lockingarms free. Fig. l'is a perspective of a detached clamp. Fig. 5 is a similar view of a door mounting'and operating means.

beted to form doorwayst,vertically superposed. V V

Each doorway- 5 is provided with a door 6 and it is one of the important objects of this invention to provide a mounting where by the door may be tightly drawn against its seat. To that end each door is pivoted at 7-7 upon the end of crank arms 8-8,

. whose shafts 9-9 are pivoted in bearings fastened on the outside of one of the jambs .3. The outer end of each shaft 9 has an .speeification of Letters Patent. a plication filed. March a, 1e15. Serial No. 11,58

eye 10 through which is slidable a lever 11 forming a handle whereby the crank shaft may be rotated and thus raise or lower the door through an are, as in Fig. 1. i

A In the presentembodiment' each door is provided with parallel Z bars 12 bolted at 13, and forming below the lower flanges a space 14; inwhich the crank arms 8-8 lie when the door is either fully open, Fig. 2, or fully closed, Fig. 3.

The bars 12 form substantial braces for the doors and as the bolts 13 pass through the upper flange of the Z bar their nuts are approximately flush with the offset lowerflange and therefore form no obstruction to the movement of the door.

The crank shaft bearing comprises an inner U-shaped strap 15 set edgewise against the jamb face and'havingoppositely directed, spaced lugs .16; The bent end of the strap 15 is set to project beyond the edge of its jamb and reoeive'the shaft 9, Fig. 2, and is clamped down by a piece of channeliron17 forming a cap through which pass fastening bolts 18.

By providing a pair of operating cranks 8-8, to each door, on one. side or jamb of the doorway, the door may be swung up or down with its sides in vertical positions. On the opposite jamb 3 is also a set of bearings 15 in which are turnable lock shafts20,eachwith an arm 21 turnable to enter the space 14 of the brace bar 12 when the door 6 is in juxtaposition therewith. The outer end of the lock shaft isprovided with an eye 22 in which is slidable a handle or lever 23.

The handle or lever 23 and the arm 21 lie in the same plane at opposite ends of their shaft 20, as also do the arms 8-8 and levers 11-11 of shafts 9-9. The crank shafts 9 and the lock shafts20 are sufliciently long to push the door 6 back from the jamb and to permit-it to' be thus turned upwardly in an arc and swung edgewise close to the inner surface of the silo wall Fig. 2.

The crank shaft handlell has at one end a sleeve or socket 24 and when the door is closed the horizontal handle 23 of shaft 20 can be shifted across the front of the door and pushed into the socket end 24: of handle 11, Fig. 1.

hen the door is closed it is firmly seated in the rabbets by means which force the several shafts 9-20 outward and thus pull on 45 lel to the plane of the wall and having the door. -Thelocking means is'as follows -Each handle 1123 is provided with a threaded eye in-whicl1 is a threaded rod an end 27 bent in a curve which is eccentric to the axis. ofuits handle bar. Thus,

26 having when the door is closed and drawn forward and the handles 11 23 .alined and joined at the socket 24, then the rods 26 are so turned that the curved ends 27' abut the caps 17 ofthe bearing. Owing to the eccentricity of the end of'the arm it acts cam-fashion and forces the shaft 8 or 20 outward. Therefore, it will be seen that I have provided means whereby each corner of the door is drawn snugly up against the jamb. The alined and inter-related handle members 11-23 of the superposed,-

closed doors thus assume positions in a common vertical plane and form a substantial ladder, the handle membersbecoming rungs thereof. The locking rods 26 when forced into abutment with the coordinate bearing cap also form a brace, of which there'is one at each end of the rung-forming members. The curved or cam ends of the locking rods bear on the caps 17 close to an adjacent.

if bolt 18 and are thereby prevented fromturning. The object of threading the lock rods 26 in the eyes 25 of the parts 11'23 is to provide for the adjustment of the cams 27 toward or from the respective caps 17, as may be necessary. I

An advantage provided by the peculiar bearing 15 is that by adjusting it toward or from the edge of its jamb ample lateral play crank arms, a door connected to the crank arms and movable therewith edgewise by the crank arms and laterally by the said axial movement, and radial handle means whereby the shaft maybe rotated, said. handle means being rotatable on the radialaxis and 7 having means to move said shaft axially.
